the sum of of two numbers is 30, the larger number is two more than three times the smaller number, what are the two numbers?

Question

I need at least the equations.

Answer 1

Let  the smaller number be   x.

Then the largernumber will be  2+3x

x+2+3x=30

4x+2=30

4x=30-2

4x=28

x=28/4

x=7

2+3x=2+21=23

The two numbers are 7 and 23.
